Modelling the Effect of Barrier Layers on the Tensile Properties of Paperboard Materials for Liquid Packaging

Abstract:

Investigations of the mechanical behaviors of the paperboard packaging materials has propelled to the forefront of the packaging industries owing to the anisotropic behavior of the paperboard materials. Paperboard materials undergo tensile forces during the creasing and folding operation. Therefore, the knowledge of the material tensile properties it is undeniably important to perform the operation without tearing the layers. Anisotropic behavior of the paperboard material is required to be addressed for the packaging material to be used effectively and efficiently. Paperboard material being anisotropic in nature have different properties in the Machine Direction (MD) and Cross Direction (CD). The paper focuses on the modelling of double layered paperboards with barrier elements either in aluminum or in Ethylene vinyl alcohol copolymers (EVOH). A numerical model of the packaging material was developed in LS-DYNA environment showing good fitting with the physical tests.
